This invention relates to new and useful improvements in a washing brush for glassware.

The invention has for an object the construction of a washing brush which is characterized by a tip brush section which is of a specific form and shape and which may be removed and replaced with tip sections of other shapes. The invention proposes to adapt the washing brush for glasses, bottles, jars and other glassware of various shapes.

Another object of this invention resides in the provision of a means for jointing the brush body and the brush tip section as a rigid unit and at ones option, in succession, as a flexible unit.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of a washing brush for glassware constructed according to this invention.

Fig. 2 is a vertical fragmentary sectional View of a portion of Fig. 1 showing specifically the.

junction of the brush body with the tip section.

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of one of the shells used in the device.

Fig. 5 is a perspective view of one of the slidable members used in the device.

Fig. 6 is a sectional view similar to Fig. 2 but illustrating these parts in a different position.

Fig. '7 is a side elevational view of another tip section which may be used in conjunction with the main body section of the brush.

The washing brush for glassware, according to this invention, includes a main body section I9 provided with bristles I I and at one end having a handle I2 by which it may be manipulated. A tip brush body section I3 with bristles II is removably mounted upon the main brush body and forms a continuation of the brush thereof. A means is provided for joining the brush body and tip body section as a rigid unit and at ones option, in succession, as a flexible unit, as will appear as this specification proceeds.

The tip section I3 is of solid cylindrical form having a rounded top. This is but one specific form of tip section which may be used according to the concepts of this invention. In Fig. 7 a conical shaped tip section I3 is illustrated with bristles II which may be substituted for the tip section l3. This is merely by way of illustration to point out that various tip sections may be provided for the main brush body to adapt the brush for cleaning various shaped hollow objects.

The means for joining said brush body and brush tip body section includes a hollow shell [5 set into each of the adjacent ends of these parts. Each shell l5 hasa cylindrical wall portion I5 forced against the wall of a bore in the body for receiving the shell. Each shell I5'has at its outer end an inturned flange I5 defining an opening I6. At .its innerend each shell I5 has several elements ll rigidly mounted upon the inner face of the wall of the shell forming an irregular configuration. As illustrated on the drawing, there are four of the members ll forming a four point star.

At the points of each of the points of the star, and formed in the wall of the shell I5, there are spring portions Ill. These spring portions are formed by cutting in from the outer edge of the shell and so dividing off strip portions of the side wall of the shell which form the spring portions. Each of the spring .portions I8 has an inward directed projection I3 arranged at the outer end of the members IT. A member I9 is slidably mounted within each shell I5 and is of a shape to engage between the members I'I. When completely pressed inwards the member I9 is adapted to have its points engage above the projections I3 of the leaf spring portions I3 to maintain the member I9 in a fixed position. The member IQ of one of the shells I5 is provided with a central hollow threaded shell portion Il-l adapted to threadedly engage a threaded solid stem I3 formed on the other section I9.

The operation of the device is as follows:

Fig. 2 illustrates the parts with the brush body and the brush tip body section connected as a rigid unit. In this figure the members I9 are held by the projecting portions Hi and the spring portions I8. The brush may be used by gripping the handle and forcing the brush portion thereof through the neck of a bottle or opening of a vessel for cleaning the same. In the event that it is desired to clean glasses in the wide base of a narrow necked container, whose crevices cannot be readily reached, it is required that the tip brush section be flexibly connected with the main brush body. To do this it is merely necessary that the tip section be gripped and pulled away from the main body section. This will cause the members I9 to disengage from the leaf spring portions Itand then the members I9 are free in the space beneath the members IT. This condition of the device is illustrated in Fig. 6. The tip brush body section may now pivot in all directions relative to the main brush body.

If desired, the parts may again be rigidly connected by aligning the tip brush section axially with the main brush body and applying pressure and turning the tip brush body section to cause the points of the members l9 to re-enter the areas between the members l1. By exerting pressure the members I9 will snap beneath the projecting portions I8 of the leaf spring portions I8 and the device will new again be in the position illustrated in Fig. 2.

The tip l3 may be removed when it is in the position shown in Fig. 2 by merely rotating it. Then the threaded socket I!) will threadedly disengaged from the threaded shank 19 The tip 13' may be substituted in place of a tip I3. Its bottom is constructed identically to the bottom portion of the tip I 3.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A washing brush for glassware, comprising a main brush body with bristles and provided with a handle, a tip brush body section with bristles, removably mounted on said main brush body and forming a continuation of the brush thereof, and means for joining said brush body and brush body section as a rigid unit and at ones option in succession as a flexible unit, comprising a hollow shell set into each of the adjacent ends of said brush body and brush body section, a member slidably mounted in and extended from each shell and rigidly connected together, means for rigidly securing said members in said shells, and means for flexibly holding said members in the shells.

2. A washing brush for glassware, comprising a main brush body with bristles and provided with a handle, a tip brush body section with bristles, removably mounted on said main brush body and forming a continuation of the brush thereof, and means for joining said brush body and brush body section as a rigid unit and at ones option in succession as a flexible unit, comprising a hollow shell as set into each of the adjacent ends of said brush body and-brush body section, a member slidably mounted in and extended from each shell and rigidly connected together, means for rigidly securing said members in said shells, and means for flexibly holding said members in the shells, said means for rigidly securing said members in said shells including leaf spring portions integral with the material of the shells and engageable with said members.
